This invention relates to rapidly operating reversing mechanisms for fluid distributlon systems and, more particularly, to-those ofv the type employed in connection with gasoline measuring devices.

One of the objects of the invention is t` provide a reversing device which requires only a slight starting movement to completely reverse itself.

Another object is to provide a combined piston diaphragm and reversing valve,y capable of reversing itself under differences o pressure. 7

Furtherobjects will appear in the course of the detailed description which will now be given in connection with the accompanying drawing in which the single figure shows, diagrammatically, a vertical section through one illustrative embodiment of the invention as applied to a gasoline measuring apparatus.

The feed Vconduit 1 is provided with branch conduits 11 yand 12 through which the liquid to be measured is supplied under pressure alternately to the measuring chambers 2 and 3. These chambers may be of any desired size, and each chamber isprovided with a vent opening 27 controlledV by a float valve 28 which closes the vent opening when the chamber is filled with the liquid to be measured. The pipe 29 connects the two vent openings, and thus it is that one chamber may vent into the other chamber. Centrally of the pipe 29 is a vent to the atmosphere indicated at 30, and this is controlledv by a' valve.

A discharge conduit 4' .communicates through the opening 21 or opening 22 in a reversing valve 'with the measuring cham-l The measuring chambers are connected by a cylindrical member and the reversing lvalve is located in- 1 Y normallyholds it raised. y

vThe operation of the parts is as follows. The measuring chamber 2 is receivingl la f bers 2 and 3, respectively.

this cylindrical connection. When the parts are positioned as shown in the drawing, the" liquidto be measured is supplied from the' conduit 1 through'the opening21 to the4 measuring chamberv2. At the same time, the

by cross walls or diaphragms 15, 15, which are spaced from each other. This provides Yseparate chambers Yin the endsof thevalve which 'communicate with vthe measuring chambers and the intake or discharge conduits according to the position of the valve.: It will thus be seenr` that when' thev liquid tov be measuredenters the chambenfit willfll the chamber until it closes the vent. -As soon asit closesv the vent', then the pressure developing on the liquid will bear against the wall land force the valve to the rightas The Vreversing mechanism includes ak lever piv'oted at 9 to the frameworkof the ap-y paratus and connected by a forked "end 13 to a pin 14 whichis'iXed to the valve. 'When the valve movesfit Vwill rock thew lever 5 on f its pivotal support 9.] The upper end ofthe lever 5 is connected at 16 to a lever varmr6, and this lever arm 6 is pivotally. connected at its upper end to ay telescoping link 7; that'is,

an4 extension l25 which is slotted at'18. The slot 18 is formedv on an arc about'the center of the pivot 16. The pin 17 Vcarried bythe link 5 extends through the slot.` The frame is provided with a stop lug 31; Surrounding the telescoping` link 7 is a compressiblespring S. viewed in the figure of the drawing, this compression spring bearing on the leverV 6 has forced the same to a position where the pin'17 engages 5the end of the slot 18, and 'the lever 5 is carriedoVer into contact with the. stopv 31. There is a corresponding lug 32 on the'other side of the frame against which the lever bears when in reversed Q. position. Mounted on the frame is a yieldingabutment 8. This abutment rests on a spring 24 which Y measuring chamber, then the pressure de- Y veloping on the liquid will force .the valveA to the right. This movement of the valve tends to close the conduit 2l supplying the liquid to the measuring chamber. T he movement of the valve swings the uppeil end of the lever 5 to the left as viewed in the figure. This movement of the lever will compress the spring S and thus store power which is utilized later to complete the movement of the valve. As the lever continues its movement to the left, the extension 25 will engage the abutment 8. When this extension engages the abutment 8, it will cause the pin 17 to move away from the end of the slot, and this will change the relative position of the pivotal connections, and cause the stored power in the spring S to operate to continue the movement of the lever 5 at its upper end until it engages the lug 32. T he abutment 8 will yield at the proper time to allow the extension 25 to pass. Thus it is that the stored power completes the shifting of the valve. By this arrangement, the stored power comes into action to complete the movement of the valve a little before communication through the opening 21 with v the conduit 11 is completely interrupted. The stored power takes up the movement of the valve before the upper end of the lever 5 arrives at its halfway position. It will thus be seen that the pressure developing on the liquid when the measuring chamber is filled with the liquid to be measured,operates directly and positively to move the valve through the iirst part of its movement, and at the same time, it operates through the means provided for storing power, for storing power to complete the movement of the valve, and it also initiates the operation of the stored power before the opening is closed through which the liquid is supplied.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims. l
